ArrayCopy(
     array:source,
     [int:index1],

)
→ array

Existing array to copy from.

Optional. Start of range of elements to copy.

Optional. End of range of elements to copy.

New copy of existing array.

Creates a new copy of an existing array.

By default the entire array is copied. You can optionally specify a range of elements to copy with the index parameters.

If only index1 is specified, the array is copied from that element to the end.

Examples:

arr = ArrayCreate(1,2,3,5,8,13,21);
arr2 = ArrayCopy(arr, 2, 4);
Output(arr2);
-> {3, 5, 8}
